Abstract

Important changes in mathematics teaching need to be made to accommodate the constantly changing students’ demography in the lower grades of Elementary Schools, particularly in mathematics competence. Teachers must contextualize mathematics learning by linking mathematics content to the culture and real-life experiences of low-grade students at the Elementary School level. Mathematical concepts taught in elementary schools shall be relevant with students' personal experiences in everyday life. Throughout history, mathematics has been widely used by different groups in a variety of ways. Arithmetic and geometry are used to meet the daily needs of society, both culturally and socially. Ethnomathematics is defined as the way people from different cultures use mathematics in their daily lives. Elementary school students are only required to learn the concept of simple two-dimensional figure in their mathematics learning. Some complexities in this topic are related to the way to deal with irregular shape of two-dimensional figures or the different length of the sides, which can actually be solved through the removal or addition of the different parts of the shape to resemble the main shape.

Abstract

This study aims to describe the pedagogical content knowledge (PCK) of mathematics student-teachers of Yogyakarta State University (YSU). The population is mathematics student-teachers of YSU in their seventh semester of the academic year 2017/2018 who undertook ethnomathematics. A sample of 31 students was established using the cluster random sampling technique. The research instrument is in the form of ethnomathematics lesson plans developed by the students. The result of the study shows that the students’ PCK in developing ethnomathematics lesson plans is generally at the level of growing PCK. Viewed from the material and pedagogical aspects, the students’ PCK falls at the level of growing PCK. The students’ PCK in developing the lesson plans of ethnomathematics of Prambanan Temple is at the level of growing PCK. The students’ PCK in developing the lesson plans of ethnomathematics of Yogyakarta Palace is at the level of pre-PCK. The students’ PCK in developing the lesson plans of ethnomathematics of Borobudur Temple is at the level of growing PCK.
